Red Hat Security Advisory Synopsis: Updated bugzilla packages fix security issues Advisory ID: RHSA-2002:109-07 Issue date: 2002-06-09 Updated on: 2002-08-20 Product: Red Hat Powertools Keywords: Cross references: Obsoletes: RHSA-2002:001 CVE Names: CAN-2002-0804 CAN-2002-0805 CAN-2002-0806 CAN-2002-0807 CAN-2002-0808 CAN-2002-0809 CAN-2002-0810 CAN-2002-0811 - --------------------------------------------------------------------- 1. Topic: A number of security-related bugs have been found in Bugzilla version 2.14. 2. Relevant releases/architectures: Red Hat Powertools 7.0 - noarch Red Hat Powertools 7.1 - noarch 3. Problem description: Bugzilla is a bug-tracking system from mozilla.org. A number of security issues have been found in version 2.14.1: Bugzilla allows remote attackers to display restricted products and components via a direct HTTP request to queryhelp.cgi. (CAN-2002-0803) Bugzilla, when configured to perform reverse DNS lookups, allows remote attackers to bypass IP restrictions by connecting from a system with a spoofed reverse DNS hostname. (CAN-2002-0804) Bugzilla creates new directories with world-writable permissions and creates the params file with world-writable permissions, which allows local users to modify the files and execute code. (CAN-2002-0805) Bugzilla allows authenticated users with editing privileges to delete other users by directly calling the editusers.cgi script with the "del" option. (CAN-2002-0806) Cross-site scripting vulnerabilities in Bugzilla could allow remote attackers to execute scripts as other Bugzilla users via the full name (real name) field, which is not properly quoted by editusers.cgi. (CAN-2002-0807) Bugzilla, when performing a mass change, sets the groupset of all bugs to the groupset of the first bug. This could inadvertently cause insecure groupset permissions to be assigned to some bugs. (CAN-2002-0808) Bugzilla does not properly handle URL-encoded field names that are generated by some browsers, which could cause certain fields to appear to be unset. This has the effect of removing group permissions on bugs when buglist.cgi is provided with the encoded field names. (CAN-2002-0809) Bugzilla directs error messages from the syncshadowdb command to the HTML output, which could leak sensitive information, including plaintext passwords, if syncshadowdb fails. (CAN-2002-0810) Bugzilla may allow remote attackers to cause a denial of service or execute certain queries via a SQL injection attack on the sort order parameter to buglist.cgi. (CAN-2002-0811) All users of Bugzilla are advised to upgrade to these errata packages containing Bugzilla version 2.14.3 which is not vulnerable to these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5. RPMs required: Red Hat Powertools 7.0: SRPMS: ftp://updates.redhat.com/7.0/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm noarch: ftp://updates.redhat.com/7.0/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm Red Hat Powertools 7.1: SRPMS: ftp://updates.redhat.com/7.1/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm noarch: ftp://updates.redhat.com/7.1/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm 6. Verification: MD5 sum Package Name - -------------------------------------------------------------------------- 1cbb82931e8bac613e465cd71ded8340 7.0/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm 3240ecaa87a0782b5b0675d7c3d245bf 7.0/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm 1cbb82931e8bac613e465cd71ded8340 7.1/en/powertools/SRPMS/bugzilla-2.14.3-1.src.rpm 3240ecaa87a0782b5b0675d7c3d245bf 7.1/en/powertools/noarch/bugzilla-2.14.3-1.noarch.rpm These packages are GPG signed by Red Hat, Inc. for security. Our key is available at: http://www.redhat.com/about/contact/pgpkey.html You can verify each package with the following command: rpm --checksig <filename> If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg <filename> 7.
